Great purchase! Can control brightness as well as color choice. Waiting for more but they are on back order . Worth the price and the wait!

Lights appear to be performing as stated. I have only had them installed for a couple of days. Time will tell if they last

I started by ordering one light and seeing how it performed in various locations (less sun to more sun) and to ensure I liked the color(s). After 2 weeks of testing I decided to order lights for the rest of the deck except the stairs that receive less than 6 hrs of sun (in April). On sunny days (in Apr-May so far) the lights will come on at dusk and last until dawn when set at the highest light settings. On a rainy day, they will shut off at some point during the middle of the night, but definitely last for the hours you'd want to use them. I have not experimented with setting the lights at lower settings, but I imagine you could set them a few levels lower and get longer output if that was truly important to you. They are definitely bright enough that you wouldn't really notice a big difference between a couple of levels of brightness. From a color perspective, the white setting still feels warm, so we've stuck with that. I am replacing existing post caps, so I'll plan to switch them in winter when I don't need the lights to help preserve the batteries. Installation was easy and I'm happy I didn't need to retrofit Trex hardwired lighting to achieve a great look. Lastly, from a service and delivery perspective, Ultra Bright Tech has been great. There was a mix up with my shipping and they proactively contacted me and refunded the difference.

Lights shipped quickly and arrived working immediately after minor assembly. 3 colors of light and 7 levels of brightness to choose from. Fit perfectly on my Trex posts and look amazing. Had an issue with 1 cap but customer service took care of it immediately. Highly recommended!

The lights look great, I like the fact that the LEDs are recessed under the cap, the magnetic adjustment system is great, and they were super easy to install! A win for my deck stairs! 5 stars for function & design.
